Spinal Epidermoid Cyst of Cauda Equina Revealed by a Hypoesthesia: Case Report and Literature Review

Spinal epidermal cysts are benign malformative tumors, which can be classified into two types: congenital forms that are often associated with other malformations. (bone, cutaneous) and exceptional acquired forms. Classically, spinal epidermoids are observed in the paraslear region or in the cerebellar ponto angle. They are rare in spinal localization, or they represent less than 1% of intrarachid tumors. We present an unusual observation of a giant squamous cell cyst of the Cauda equina in a 23-year-old patient revealed by back pain and hyposthesia. A complete, total removal is the treatment of choice.
